Post Beatles break-up, John Lennon said that those people clamouring for a Beatles reuninon could just put their own Beatles album together - one track from a Lennon solo album, another from one of Paul's, one from George's and so on...
In this age of iPods this is now an intriguing possibility, and putting together 1970s Beatles albums is surprisingly satisfying. To my ears, for example, the first 1970s Beatles album, possibly called 'Instant Karma', would have had the following tracks on it:
1 Instant Karma
2 Every Night
4 My Sweet Lord
6 Jealous Guy
7 Maybe I'm Amazed
1 Too Many People
4 Uncle Albert / Admiral Halsey
5 All Things Must Pass
6 The Back Seat of My Car
7 Oh My Love
And I think it would have made a good album too.
This little exercise got me thinking about why Lennon and McCartney's 70s solo albums ended up being inferior to their Beatles ones. Rock critics usually attribute this to the lack of the Lennon-McCartney dynamic and intra-band competition; I think this is partly true, but I also have a slightly different angle on it.
As a proper solo artist (i.e., not seven-writers-on-my-record James Blunt), you have to write 10-14 songs on your own to fill an album. But whilst in the Beatles, John and Paul only had to contribute 5 or 6 tracks to each album (and let George get a couple in). Obviously it's much easier to write 5 good songs a year than 14, and you can devote more time to producing them. When the Beatles broke up, the demands of putting out one solo record a year (or sometimes two) meant that John and Paul had to fill whole albums with material - something that is much more difficult to do and which they weren't used to. Which invariably led to fillers like Lennon's Oh Yoko (which has the same melody as Three Blind Mice), or McCartney songs with titles like Single Pigeon (classic).
But when you take 5 or 6 of their better efforts from their solo albums and put them in the same pot, as I did above, you do end up with a record that shapes up pretty well, and had George Martin been at the wheel, might have sounded damn good. Don't think Single Pigeon would have ended up on a 70s Beatles album somehow though.
